2 For your safety
Read the chapter on safety and follow the instructions in order to protect from personal injury and damage to
equipment.
Limitation of liability
All the components are supplied in particular hardware and software configurations appropriate for the
application. Unauthorized modifications and changes to the hardware or software configuration, which go
beyond the documented options, are prohibited and nullify the liability of Beckhoff Automation GmbH & Co.
KG.
In addition, the following actions are excluded from the liability of Beckhoff Automation GmbH & Co. KG:
• Failure to comply with this documentation.
• Improper use.
• Use of untrained personnel.
• Use of unauthorized replacement parts.
2.1 Intended use
The Embedded PC is a control system and is intended for mounting on a DIN rail in a control cabinet or
terminal box. The Embedded PC series is used in conjunction with Bus Terminals for recording digital or
analog signals from sensors and transferring them to actuators or higher-level controllers.
The Embedded PC is designed for a working environment that meets the requirements of protection class
IP20. This involves finger protection and protection against solid foreign objects up to 12.5 mm, but not
protection against water. Operation of the devices in wet and dusty environments is not permitted, unless
specified otherwise. The specified limits for electrical and technical data must be adhered to.
Improper use
The Embedded PC is not suitable for operation in the following areas:
• Potentially explosive atmospheres.
• Areas with an aggressive environment, e.g. aggressive gases or chemicals.
• Living areas. If the devices are to be used in living areas, the relevant standards and guidelines for
interference emissions must be adhered to, and the devices must be installed in housings or control
boxes with suitable shielding.
2.2 Staff qualification
All operations involving Beckhoff software and hardware may only be carried out by qualified personnel with
knowledge of control and automation engineering. The qualified personnel must have knowledge of the
administration of the Industrial PC and the associated network.
All interventions must be carried out with knowledge of control programming, and the qualified personnel
must be familiar with the current standards and guidelines for the automation environment.
2.3 Safety instructions
The following safety instructions must be followed during installation and working with networks and the
software.
Mounting
• Never work on live equipment. Always switch off the power supply for the device before installation,
troubleshooting or maintenance. Protect the device against unintentional switching on.
For your safety
CX8190 9Version: 1.5
• Observe the relevant accident prevention regulations for your machine (e.g. the BGV A 3, electrical
systems and equipment).
• Ensure standard-compliant connection and avoid risks to personnel. Ensure that data and supply
cables are laid in a standard-compliant manner and ensure correct pin assignment.
• Observe the relevant EMC guidelines for your application.
• Avoid polarity reversal of the data and supply cables, as this may cause damage to the equipment.
• The devices contain electronic components, which may be destroyed by electrostatic discharge when
touched. Observe the safety precautions against electrostatic discharge according to DIN EN
61340-5-1/-3.
Working with networks
• Restrict access to all devices to an authorized circle of persons.
• Change the default passwords to reduce the risk of unauthorized access.
• Protect the devices with a firewall.
• Apply the IT security precautions according to IEC 62443, in order to limit access to and control of
devices and networks.
Working with the software
• The sensitivity of a PC against malicious software increases with the number of installed and active
software.
• Uninstall or disable unnecessary software.

2.4 Notes on information security
The products of Beckhoff Automation GmbH & Co. KG (Beckhoff), insofar as they can be accessed online,
are equipped with security functions that support the secure operation of plants, systems, machines and
networks. Despite the security functions, the creation, implementation and constant updating of a holistic
security concept for the operation are necessary to protect the respective plant, system, machine and
networks against cyber threats. The products sold by Beckhoff are only part of the overall security concept.
The customer is responsible for preventing unauthorized access by third parties to its equipment, systems,
machines and networks. The latter should be connected to the corporate network or the Internet only if
appropriate protective measures have been set up.
In addition, the recommendations from Beckhoff regarding appropriate protective measures should be
observed. Further information regarding information security and industrial security can be found in our
https://www.beckhoff.com/secguide.
Beckhoff products and solutions undergo continuous further development. This also applies to security
functions. In light of this continuous further development, Beckhoff expressly recommends that the products
are kept up to date at all times and that updates are installed for the products once they have been made
available. Using outdated or unsupported product versions can increase the risk of cyber threats.

Transport and storage
CX819010 Version: 1.5
3 Transport and storage
Transport
NOTE
Short circuit due to moisture
Moisture can form during transport in cold weather or in the event of large temperature fluctuations.
Avoid moisture formation (condensation) in the Embedded PC, and leave it to adjust to room temperature
slowly. If condensation has occurred, wait at least 12 hours before switching on the Embedded PC.
Despite the robust design of the unit, the components are sensitive to strong vibrations and impacts. During
transport the Embedded PC must be protected from
• mechanical stress and
• use the original packaging.
Table1: Dimensions and weight of the CX8190 Embedded PC.
CX8190
Dimensions (W x H x D) 71 mm x 100 mm x 73 mm
Weight approx. 230 g
Storage
• Remove the battery from the Embedded PC if storage temperatures exceed 60°C. The battery should
be stored separate from the Embedded PC in a dry environment at a temperature between 0°C and
30°C.
The preset date and time are lost if the battery is removed.
